How do you convert a value of a numeric up down to a variable?
View 1 RepliesI have a variable (double) which has a constantly (infinitely) changing value. I would like to store all the values of this ONE variable into an array. My variable and array are:
Dim x as Double
Private y as Double() = New Double (499) {}

sRndMessageNumber = "sNewMessage" & CInt(Int((3 - 1 + 1) * Rnd() + 1))
I want to Calculate a number between 1 to 3 and then call the variable sNewMessage2 for example. So how to convert from string to variable?
I'm working on a home project using DirectShow.Net. to learn some VB.net. Most of the examples I've found have all been in C# so I'm looking through code for ideas and converting where I need to. I keep stumbling upon these declarations and I'm unsure how to convert it to a VB.Net statement.[code]Then the second part seems to be assigning the value but as its made up of two parts im unsure how that works?
View 2 RepliesI'm programming a basic slot machine in Visual basic, and want to use a for loop to randomly choose the image for each slot, display the image in each slot, and change the slotName variable (so I can check later on which symbols are in the slots) for each slot. The problem I'm finding with a for loop is that the variables and objects for each slot have different names (slot1Name, slot2Name, slot3Name, lblSlot1, lblSlot2, lblSlot3, etc). Is there any way I could have could something like:
currentSlotName = "slot" & i & "Name"
This is the code at the moment, this code is repeated (with different variable and object names), for each of the 3 slots, which is pretty inefficient.
' Randomise numbers and assign images to slots based on random numbers, if the hold isn't on
' Slot 1
If Not held1 Then
slot1Value = Int(Rnd() * numbersGenerated + 0.5)
Select Case slot1Value

Convert String Variable to an Integer?
I tried this[code]...
Here's my problem :
Let say I have a variable called A
Which value is 100 ( A = 100)
In a form, I have a textbox, where I want to enter a variable name
textbox1.text="A" for example
Then I want to display the value of that variable
msgbox (somefunction(textbox1.text)), which will popup 100
I read some info about Reflection, but they all seems to refer to controls and not simple variable

I am developing an application which initially allows the user to browse and select a save location. The selected path is assigned to a public variable which is used with concatenation to crate folder for saving user input data. How can I change the path string to a constant so the user can run the program again without having to run setup routine unless they want to change the save location?
View 1 RepliesI am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.
At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the
decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.
The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the
conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).

i dont know how to assign variables and im juist totally lost right now and this is due today and i was sick 2 weeks and am 2 chapters back.
I am trying to filter fields in a table that contain percent (%) and apostrophe (') characters. I kow that to filter an apostrophe you need to add another apostrophe (''). However, when a text contains the percent (%) character in combination with an apostrophe (') character, an exception is thrown. Also, when using the % character in a filter string, it will be function as an "*" (fields starting or ending with). I need the % to be considered as a character whenever the % makes part of a string in the field.

I need help getting a progress bar to show percent in it. I want to have the percent in the middle of the progress bar, like is sometimes seen in a few programs. I have googled this, and can't find anything. I found something on The CodeProject, but it was just a label and drawing a rectangle behind it. I would like the actual progress bar that is available through the toolbox.
View 5 RepliesIs possible get the percent of a word in the content of a richtexbox? if yes, can you give me some example?
For example if I have 100 words in a richtextbox and I want to know what is the percent of a word in this content (for example if a word called "music" is repeated 10 times = 10%. If this is not possible in a richtextbox, is possible in other box like textbox?
i was wondering if it's possible to do such:
'form location Me.Location = New Point(10%, 50%)
i know this code doesn't work as it looks, just loads the location by pixels. this is just a question, hopefully with a working code for a marked answer..so much work to do and so many choices to choose from.
the code below shows an if statement that is determining a customer type and a discount percent for that customer.But when I run the code it only ever reads the first discount percent even though the allocated price range is above the first discount percents range and should therefore give the second discount percent and i cant figure out why it is not using the second discount percent in any of the bronze, silver or gold statements.

i followed a few tutorials on here to create a calculator in VB.NET. But i am having trouble getting the percent button working properly.I have tried to come up with some things but nothing i have tried is working.I used this Basic Calculator VB.Net and this one Create a Calculator.I have searched google for an answer but it seems what i have is not working.Im not sure exactly what is needed so i will post all of the code i have.

View 4 RepliesI have this issue where for every 1% below a 95% threshold a charge of 67 is added. For instance if the percentage drops to 70% I would need a method of totalling the charge for every percent.
Would I need to use a Do....While loop then the if...then statements?
We were given this and for some reason I can't get this to work right. Here is the whole thing:The following code should display three rows of percent signs in the msgLabel. The first row should contain one percent sign, the second row should contain two percent signs, and the third row should contain three percent signs. However, the code is not working correctly.
